Method and system for identifying authoritative information resources in an environment with content-based links between information resources
First Claim
1. A computer program product, for use with a computer system, for directing the computer system to execute a search of information resources, the resources having content-based links between each other, to identify a desired subset of the information resources which satisfy a desired criterion, the computer program product comprising:
- a computer-readable medium;
means, provided on the recording medium, for directing the computer system to identify an initial set of information resources;
means, provided on the recording medium, for directing the computer system to define initial authoritativeness information for the initial set;
means, provided on the recording medium, for directing the computer system to use the initial authoritativeness information as input authoritativeness information, to execute the steps of;
(i) producing first authoritativeness information about a set of information resources pointed to by links in resources of the input set, and(ii) producing second authoritativeness information about a set of information resources having links that point to resources of the input set; and
means, provided on the recording medium, for directing the computer system to produce a final set of information resources based on the first and second authoritativeness information.

Abstract
A system and method are provided for searching for desired items from a network of information resources. In particular, the system and method have advantageous applicability to searching for World Wide Web pages having desired content. An initial set of pages are selected, preferably by running a conventional keyword-based query, and then further selecting pages pointing to, or pointed to from, the pages found by the keyword-based query. Alternatively, the invention may be applied to a single page, where the initial set includes pages pointed to by the single page and pages which point to the single page. Then, iteratively, authoritativeness values are computed for the pages of the initial set, based on the number of links to and from the pages. One or more communities, or "neighborhoods", of related pages are defined based on the authoritativeness values thus produced. Such communities of pages are likely to be of particular interest and value to the user who is interested in the keyword-based query or the single page.

20. A method for executing a search of information resources, the resources having content-based links between each other, to identify a desired subset of the information resources which satisfy a desired criterion, the method comprising the steps of:
-
identifying an initial set of information resources; defining initial authoritativeness information for the initial set; using the initial authoritativeness information as input authoritativeness information, executing the steps of; (i) producing first authoritativeness information about a set of information resources pointed to by links in resources of the input set, and (ii) producing second authoritativeness information about a set of information resources having links that point to resources of the input set; and producing a final set of information resources based on the first and second authoritativeness information. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A system for executing a search of information resources, the resources having content-based links between each other, to identify a desired subset of the information resources which satisfy a desired criterion, the system comprising:
-
means for identifying an initial set of information resources; means for defining initial authoritativeness information for the initial set; means for using the initial authoritativeness information as input authoritativeness information, to execute the steps of; (i) producing first authoritativeness information about a set of information resources pointed to by links in resources of the input set, and (ii) producing second authoritativeness information about a set of information resources having links that point to resources of the input set; and means for producing a final set of information resources based on the first and second authoritativeness information. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
